Z-splitter prism achieves resolution deep in sample Historically, when scientists and clinicians looked through a traditional microscope, they saw only a thin 2D plane of a sample. This was unhelpful for understanding complex cellular processes or the relationships that various systems had to each other. While it was possible to cast various wavelengths of light deep into brain tissue, for example, researchers had to contend with the shallow and...

UV light helps to set marine life clock Human swimmers may need a waterproof watch to tell time while bathing in the ocean, but certain marine species whose internal clocks are regulated by light do not. With this circadian regulation in mind, researchers at the University of Vienna decided to measure the effects of changing light on the movements and other activities of a worm that lives in coastal waters in temperate zones of the Bay...
